Sympatric speciation is: . 1. initiated by the appearance of a geographic barrier 2. the process by which most animal species have evolved especially 3. important in the evolution of island species 4. the appearance of a new species in the same area

The right answer is option 4

Explanation:

Sympatric speciation is the evolving of an old species into a new one while the older species still exists thus making both species coexist in the same geographic region. The differing factor of Sympatric speciation from other types is the lack of geographical constraint to interbreeding. Other types of speciation are Allopatric and Parapatric speciations.
